10 Essential Roof Inspection Checklist Items for Texas Commercial Properties

Keeping your commercial roof in good shape is necessary in Texas, where heat, hail, and storms can cause serious damage quickly. This easy-to-follow Roof Inspection Checklist covers the top 10 things to look for during a roof inspection. Whether you’re a property owner or manager, these tips will help you catch problems early, avoid expensive repairs, and keep your building safe year-round.

Why Roof Inspections Matter in Texas

Texas isn’t known for being gentle on buildings. With scorching summers, surprise hail storms, and tornado-level winds, commercial properties in Texas need extra attention, especially their roofs. Business owners often forget about the roof until there’s a problem, but it’s too late by then.

Whether you’re in Houston, Dallas, Austin, San Antonio, or even smaller towns like Midland or Waco, your commercial roof is one of your most valuable assets. It protects everything underneath—from inventory to tenants to your bottom line. That’s why regular roof inspections are a smart and necessary part of building maintenance. And for a better roof, you need to maintain a roof inspection checklist

This guide answers those questions with real-world, easy-to-understand tips, created for Texans like you.

1. Check for Visible Roof Damage

Start with the roof inspection checklist, a general look over the roof—either safely on your own (flat roofs) or by hiring a pro. You’re looking for anything out of place:

• Torn, cracked, or missing shingles
• Damaged tiles or panels (especially with metal roofs)
• Soft or sagging areas
• Debris buildup (branches, trash, tools left behind)

Storms in Texas can knock things around quickly. Even minor hail can puncture or bruise roofing materials, while high winds can peel up edges or dislodge protective layers.

Tip: Use a drone for a safe, full-roof view if it’s too risky to climb up.

2. Look for Water Ponding or Pooling

Flat commercial roofs are especially prone to pooling water, a major red flag. If water sits on the roof for more than 48 hours, it means the drainage isn’t working right.

Why is this serious?

• Water adds unnecessary weight to the structure
• It encourages mold, mildew, and rot
• It leads to quicker surface breakdown

Pooling often forms in low spots caused by settling or poor design. Texas storms often dump inches of rain quickly, so drainage must work fast.

Fix it early: Re-grade low spots or install tapered insulation systems to direct water toward drains.

3. Inspect Flashing and Roof Edges

Flashing is the metal or rubber material used to seal joints, like where the roof meets walls, skylights, or chimneys. In Texas, flashing often suffers from:

• UV damage
• Rust from humidity
• Wind lift during storms

Loose flashing allows water to sneak behind protective layers and causes slow, hidden leaks. Look for rust, bent pieces, or visible gaps.

Quick fix: If you see exposed nails or cracks, they need to be resealed ASAP.

4. Examine Roof Surface for Cracks or Blisters

Blisters and cracks are like bruises on your roof—they may not look dangerous now, but will get worse. These forms are due to:

• Trapped moisture
• UV breakdown
• Aging materials

Especially in places like El Paso or Lubbock, where sun exposure is brutal, you’ll find this on flat roofs made of TPO, modified bitumen, or rubber.

Watch for: Raised bumps, flaking surfaces, or long cracks in straight lines (especially near seams).

5. Evaluate Roof Drainage Systems

Drainage isn’t just about gutters. For commercial roofs, you also have this in your roof inspection checklist:

• Inner drains
• Roof scuppers
• Parapet wall drainage holes
• Downspouts and filter baskets

Clogged drains are one of the biggest causes of leaks and premature roof failure. You can often trace wet ceilings inside to a simple clogged drain on the roof.

What to do: Remove leaves, nests, or sludge. If water isn’t moving, get it inspected—don’t wait until interior damage appears.

6. Inspect Seals Around Vents and HVAC Units

Almost every commercial roof has pipes, vents, fans, or HVAC systems poking through it. Each of those is a leak waiting to happen—unless properly sealed.

Look for:

• Dried or cracked sealant
• Loose flashing or metal boots
• Soft or discolored roof surface around equipment

In the Texas heat, sealants expand and crack. These seals need checking at least twice a year.

Tip: Use high-temp, UV-resistant sealants when repairing, not cheap caulking that fails in a few months.

7. Check for Signs of Mold or Algae Growth

Texas humidity, especially in Houston and along the Gulf Coast, means mold and algae are a real threat. Mold often shows up as:

• Dark streaks
• Green patches
• Slippery roof areas
• Musty smells inside the building

This isn’t just a cosmetic issue—it can damage roof material and make it dangerous for maintenance crews.

✅ What helps: Apply zinc or copper strips to prevent growth. Soft wash systems are safer than pressure washing for delicate roofs.

8. Assess Roof Membrane Integrity

For TPO, PVC, EPDM, and other membrane systems (common in commercial buildings), check for:

• Seam lifts
• Membrane shrinkage
• Rips, tears, or punctures
• Discoloration from standing water or UV rays

Pro tip: Use thermal imaging to spot moisture under the membrane—something you can’t see with the eye.

9. Examine Roof Penetrations

Roof penetrations = anything that “pokes through” your roof. This includes:

• Skylights
• Plumbing vents
• Exhaust fans
• Satellite mounts
• Solar panel brackets

Every one of these needs flashing and sealing. If not done right, they allow water inside.

Inspect for: Cracked bases, loose screws, or materials pulling away from the penetration.

10. Check Interior Ceilings for Water Stains

Don’t forget to check inside your building. Water spots often show up on:

• Drop ceiling tiles
• Top-floor drywall
• Around light fixtures or vents

Also, check for:

• Musty odors
• Paint bubbling or peeling
• Sagging panels

By the time a stain appears inside, your roof leak may be weeks old. Early inspections can prevent that, so you should follow the roof inspection checklist

Common Texas Roof Problems and How to Prevent Them

Texas-specific threats include:

• Hail damage: Leads to punctures, broken shingles, dented metal panels
• High winds: Can pull up flat roof edges, peel shingles, or dislodge gutters
• UV damage: Bakes and cracks roofing materials
• Flash floods: Test your drainage systems
• Sudden freezes (Yes, even in Texas): Cause ice damming and flashing gaps

Prevention means inspections in spring and fall, and immediately after severe weather.

How Often Should You Schedule Roof Inspections in Texas?

Here’s a helpful schedule for Texas commercial buildings:

Situation	Inspection Frequency
Normal conditions	Twice a year (Spring + Fall)
After major storm or hail event	Within 48-72 hours
Before leasing/selling property	Before listing
Before or after repairs/upgrades	Always

Use reminders or property maintenance apps to stay on schedule.

Hiring a Roof Inspector vs. DIY: What’s Best for Your Property?

DIY is okay for quick visual checks, especially flat roofs.

Hire a pro when:

• You don’t have safe roof access
• You need thermal imaging or moisture mapping
• Insurance requires a certified inspection
• You’re buying or selling the building

Choose roofers with Commercial Roofing Services and Texas licensing. Ask about inspection reports with photos, detailed findings, and recommended fixes.

Final Thoughts: Stay Ahead of Repairs with a Proactive Checklist

Your roof is not just a cover—it’s your first line of defense. Ignoring it can cost you tens of thousands of dollars in water damage, lost tenants, or interrupted operations.

By using this 10-point inspection checklist at least twice a year, Texas business owners can:

• Avoid costly emergency repairs
• Extend roof lifespan by 5 to 10 years
• Lower energy bills by fixing insulation leaks
• Protect tenants, customers, and staff

Being proactive is always cheaper than fixing a leak after it ruins your ceiling, drywall, or electronics.
